Just tried a Pure One filter for the first time and was suprised how small the oil supply holes were on the filter. The number of holes was the same but much smaller. Has any one else noticed this, and do you think it has good enough flow capabilities through the filter. I have been using EAO 32's on my 5.3L Chevy, but since I don't get true value from them(change every 5000mi.) I decided that $13.00 a filter was not justified on short OCI's. I use either Amsoil XL 5w30 or PP 5w30. Thanks.
